Anything about the Dm542t or Dm542a???http://www.mycncuk.com/threads/12576-Anything-about-the-Dm542t-or-Dm542a?goto=newpost
Thu, 14 Feb 2019 22:32:58 GMTHello! I've been really interested in buying one of these for my cnc. I've seen a lot of people using it and it seems that it's a really reliable stepper driver. Now I got a few questions, first off, does anyone recommend it and are there any superior specs that make it particularly outstanding (would you recommend something else)? Is there a difference between the "t" model and the "a" model? And is there any reliable distributors one would recommend?(reason being, I impulsively bought 3 of the dm542t from a sketchy distributor and had to get a refund from Amazon).

Thanks so much in advance!!!

...so amazingly I just won a Geco G540 4-Axis Digital Step Drive on a facebook comp.

Im hoping to start a new build soon, im yet to consult with the guy who did my electrics for my last build but the website says 3.5a per axis. I have no real idea if that's a lot or a little or if I should look at trying to upgrade if I can. or save it for another project. my plan is a 1220x660 work area built in steel 2.2kw spindle with csmio-m controller.

Sorry for I am a newbie on CNC...

I am trying to connect a motor driver with 4 wires names: DIR+, DIR-, PUL+ and PUL- to a control board that only have 3 wires: Axis_enable, DIR and STEP...

I am missing something, are these not compatible or is it that DIR- and PUL- should be grounded and STEP=PUL+ with DIR=DIR+?

Thanks!

Cyrille

Also, if I use a filter on the output side of the VFD, would this protect both the VFD and the motor?

Thu, 27 Dec 2018 18:30:29 GMTHi Guys

I decided I wanted to upgrade my nema 23 425 motors to nema 34's. Figuring it would be a simple job I went about ordering new motors and fitted them today. However since fitting them it's taken my machine out of action.

I have leadshine dm856 drivers hooked up to 48v power suppliers. Prior to the switch I was able to jog at 8000mm a min easily enough. Now I can't go past 500 without jamming. Acceleration is set to 50... steps haven't changed and it's a 1605 ball screw machine.

If I jog it just seems to jam up

...Hello All

Can anyone explain the difference/benefits of the Huanyang Gt series vfd over their Hy series vfd ? Thanks in advance.

I'm improving my mill and am looking to add spindle speed control from LinuxCNC to my Sieg X2 mill. I don't really want to change the spindle to AC and go the VFD route so am looking to use the PWM output to control everything. So was wondering if anyone had done this and how they had done it? I've found links to the Mesa spindle controller ( http://store.mesanet.com/index.php?r...product_id=205 ) and wondered if this then plugs into my mills transformer in some way to replace the manual variable resistor that controls speed. If it does has anyone got wiring plans or photos?

If there are better ways to do this then please let me know too.

Specs on the motor are in the attached photo.

I wish to fit a z axis probe to my newly acquired ancient Chinese 3020 mill, I am running mach3 and the controller has the yoocnc t62-3ax board. I have got it working by connecting the probe directly to pin 15 of my parallel port plug on the computer and allocating it in the software, it works ok but I suspect I need to isolate it somehow.
any help gratefully appreciated
John
